Definitions

  • the present application relates to the field of radio communications, and in particular, to methods and apparatuses for channel state information (CSI) reporting, a terminal device, a network device and a storage medium.
  • CSI channel state information
  • each terminal may be configured with multiple antenna panels, and each of the panels corresponds to a beam direction.
  • a terminal may only select one antenna panel for uplink transmission at a moment, that is, only one beam direction may be generated.
  • some terminals are configured with multiple antenna panels, allowing the terminal to use multiple antenna panels to perform transmission simultaneously in their respective beam directions. This way helps to improve an uplink transmission rate, improve a reliability of uplink transmission and enhance uplink coverage.
  • an NR system Based on a configuration of a base station, an NR system supports a terminal to report a capability value index while reporting a synchronization signal/physical broadcast channel (PBCH) block resource indicator (SSBRI) or a channel state information reference signal resource indicator (CRI), layer 1 reference signal received power (L1-RSRP) or a layer 1 signal-to-noise and interference ratio (L1-SINR) (i.e., SSBRI/CRI + L1-RSRP/L1-SINR).
  • PBCH synchronization signal/physical broadcast channel
  • SSBRI synchronization signal/physical broadcast channel
  • CRI channel state information reference signal resource indicator
  • L1-RSRP layer 1 reference signal received power
  • L1-SINR layer 1 signal-to-noise and interference ratio
  • a capability corresponding to the capability value index is a maximum number of sounding reference signal (SRS) antenna ports that a corresponding antenna panel may support. Different capability value indexes correspond to different maximum number of SRS antenna
  • the terminal determines a correspondence between the capability value index and a beam index (for example, a SSBRI or a CRI) by itself.
  • a beam index for example, a SSBRI or a CRI
  • the terminal reports a capability value index corresponding to the SSBRI/CRI to the base station when reporting SSBRI/CRI + L1-RSRP/L1-SINR, and the base station may know an uplink antenna panel corresponding to the SSBRI/CRI.
  • values of SSBRI/CSI in one CSI report are different, that is, a channel state information reference signal (CSI-RS) resource or an SSB resource may only report one corresponding capability value index, which may also be understood as a CSI-RS or SSB may only report one corresponding capability value index.
  • CSI-RS channel state information reference signal
  • the base station may only know which downlink (DL) reference signals (RSs) may be used as references for an uplink configuration corresponding to which type of a maximum number of SRS antenna ports, and cannot know which DL RSs correspond to which antenna panels. Therefore, the traditional mechanism cannot be used to configure a terminal to perform transmission simultaneously on multiple uplink antenna panels.
  • DL downlink
  • RSs downlink reference signals
